Chartjs tooltip and draw line separatly

Question

Chartjs 3.6.1; typescript 4.3.5

I would like to draw a vertical line on chartJs, where the user clicked (once). I can draw a line in the chart.options.onClick() function, it's no problem, but:

• by default, it's removed when I move my mouse
• I can add chart.options.events: ['click'],, but in this case the tooltip's behaviour changes as well: on click, the tooltip appears, then I have to click again to draw my line as well. Also, the line is go through the tooltip which is ugly
• If I disable the tooltip, my line will never be rendered

This question is a good base: Moving vertical line when hovering over the chart using chart.js With that fiddle included: http://jsfiddle.net/dbyze2ga/658/ (It uses older chartJs version, but it's okay I think)

Is there a solution to leave that line after I move the mouse? Best could be to just extend with a line on click, and displays tooltips on mouse hover; worst case is draw the line and tooltip on click, but not by overlapping each other
